Final answer:
Temporal coherence/cooccurrence of synaptic activity refers to the synchronization of synaptic activity between different neurons.
Step-by-step explanation:
Temporal coherence/cooccurrence of synaptic activity refers to the synchronization of synaptic activity between different neurons. It is the relationship of multiple action potentials from a single cell resulting in a significant change in the membrane potential.
Spatial arrangement of synapses within a neuron, strength of the synaptic connections between neurons, and the rate at which synaptic vesicles release neurotransmitters are not the concepts referred to by temporal coherence/cooccurrence of synaptic activity.
